It can also be used as a temporary system prior to the installation of an impressed current system. Zinc ribbon anodes are produced according to ASTM-B***8 type I and type II alloy standard in the shape of diamond. Zinc ribbon anode can be used in fresh water, sea water environments, also can be used in underground structures.

All dimensions and weights are nominal. 2. Wire core is galvanized steel. 3. Longer coil sizes are available on special order. Standard coil lengths of ***0&#**9; and ***0&#**9; are also available. Zinc Grounding Rod Zinc grounding rod is mainly used in the grounding system of petrochemical, natural gas, transformer substation, railway and civil aviation facilities. There are two typical applications of the rod: 1. As a substitution for copper or copper coated power grounding rods in order to avoid bimetallic corrosion of associated ferrous structures. 2. In mitigation of voltages which may be introduced in pipelines by adjacent overhead AC power lines. Pipelines may be ground bed via Zinc electrodes without attendant disruption of pipeline cathodic protection General Specification Dimensions(mm) Weight (g/cm) OD(mm) ID(mm) *3.*7 2.0 *1.*1 *9.*5 3.4 *0.*9 *1.*3 3.4 *5.*0 *6.*7 3.4 *9.*9 *3.*0 3.4 *2.*2 *9.*5 4.8 *8.*2 *1.*0 4.8 **8.*1 The length of the anode can be made according to customer&#**9;s request. Zinc Grounding Electrodes Zinc grounding cell consist of two rod anodes which are separated by insulated spacers it prevents the system to be destroyed by strong current by welding the cell on the side of the insulated setting.
